Mount Lyell is the highest peak in Yosemite National Park. Its summit rises just east of the Pacific Crest Trail near the June Lake Loop Road, a popular tourist road that winds around many of the area's pleasant mountain lakes. The road makes Lyell easy to access, but also creates a tremendous amount of tourist traffic. There are many peaks in the area only slightly lower than Lyell, and all can be climbed via an extensive network of trails.
